Polyester resin (Unsaturated Polyester Resin) is a kind of liquid resin that unsaturated polyester is dissolved by polymeric monomer having the groups of vinyl or allyl. Polyester resin turns into insoluble and infusible plastics by hardening through cross-linking reaction and rising temperature at the room temperature by adding peroxide catalyst and when it is heated or when it is mixed with peroxide catalyst and accelerator.
Also, Polyester resin turns into FRP if the resin is spread and impregnated through reinforced material such as glassfiber by lamination before it is gelled.
Unsaturated polyester resin holds an important position among thermosetting resins and its demand is expanding widely for decorative panels, bathtubs, septic tank, electric insulators, ships, corrugated panels, and automobile parts, etc.
